Given:
- Radius of the orbit of S1: 10^4 km
- Period of revolution of S1: 1 hour
- Period of revolution of S2: 8 hours

To Find:
(a) The speed of S2 relative to S1
(b) The angular speed of S2 as observed by an astronaut in S1

Solution:

1. Speed of S1:
The speed of an object in circular motion can be calculated using the formula:
Speed = 2πr / T
where r is the radius of the orbit and T is the period of revolution.

Substituting the given values:
Speed of S1 = 2π(10^4 km) / 1 hour = 20π(10^4) km/h

2. Speed of S2:
Since S1 and S2 are revolving in the same sense, the relative speed of S2 with respect to S1 can be calculated by subtracting the speed of S1 from the speed of S2.

Relative Speed of S2 = Speed of S2 - Speed of S1

We know that the time period of S2 is 8 hours. Using the formula mentioned above, we can find the speed of S2.

Speed of S2 = 2πr / T = 2π(10^4 km) / 8 hours = π(10^4) / 4 km/h

Now, substituting the values in the relative speed formula:

Relative Speed of S2 = π(10^4) / 4 km/h - 20π(10^4) km/h

Simplifying the expression:

Relative Speed of S2 = (π(10^4) - 80π(10^4)) km/h = -79π(10^4) km/h

Therefore, the speed of S2 relative to S1 is -79π(10^4) km/h.

3. Angular Speed of S2:
The angular speed of S2 as observed by an astronaut in S1 can be calculated using the formula:
Angular Speed = 2π / T
where T is the period of revolution.

Substituting the given value:
Angular Speed of S2 = 2π / 8 hours = π / 4 radians per hour

Therefore, the angular speed of S2 as observed by an astronaut in S1 is π / 4 radians per hour.
